Astronomers Wonder About a Lack of planets in Globular Cluster
SOYUZ PREPARES TO DOCK WITH SPACE STATION
The Progress cargo ship currently docked to the International Space Station was disconnected from the docking port, and moved to a lower orbit (where it will burn up in the atmosphere) earlier this morning to make room for the approaching Soyuz capsule carrying the first permanent inhabitants of the station - Expedition 1. The ship is expected to dock Thursday at 9:25am GMT.
OPPORTUNITY TO BUY CHEAP RUSSIAN ROCKETS
The chief of Russia's nuclear program announced yesterday that he has hundreds of rockets for sale for launching satellites - at discount prices. The most likely candidates for sale are the SS-18 rockets, or Stilettos, as they are called in the West. Russia can't afford to maintain the enormous nuclear arsenal it inherited after the breakup. It's estimated these rockets would cost 1/6th the price of conventional purpose built rocket.
CHINA LAUNCHES ITS FIRST NAVIGATION SATELLITE
The official Xinhua News Agency reported yesterday that China has successfully launched its first navigation positioning satellite, the Beidou Navigation Test Satellite-1 (BNTS-1), on board a Changzheng-3A rocket. The launch occurred at 4:02pm GMT on October 30th, and the satellite was delivered into orbit 27 minutes later. The Beidou will serve the same purpose as the US-based GPS system, which enables people on the ground to know their exact position.
ASTRONOMERS WONDER ABOUT A LACK OF planets IN GLOBULAR CLUSTER
Astronomers using the Hubble Space Telescope were surprised to find that they were unable to find any extrasolar planets in the globular star cluster 47 Tucanae, which contains 35,000 stars - they expected to find 17. Hubble was trained on the cluster 15,000 light years away, and it would be able to monitor slight movements in any of the stars, indicating a planet. The fact that they didn't find any indicates the possibility that planet formation works differently in different locations in the galaxy.
